Let's see...

I'm a bat and I fly into a room full of lightning and ozone. I panic. My
mind's blown. I'm flying randomly anywhere I can to try and get away from
wherever's happening. I'm beating my head against the wall just trying to
make sense of the chaos into which I've just flown. "Aaaggghhh!"

Suddenly, everything's quiet. I sense an opening, zoom over to it, and I get
out of there fast. "What *was* that?" I'm asking myself. "Did I just have a
mental breakdown?"
"It was was so noisy I couldn't even hear my own sonar!", etc.

I think the Tesla coil probably jammed the bat's entire brain and distorted
its entire perception of reality ;) It's probably attending bat-therapy
*right now* ;)
